Our company has engaged in the research and development of dry powder inhaler since 1994. And we have accumulated extensive experience in formulation, filling, device design, etc. By far we have applied and granted a number of patents both domestic and worldwide. Our products cover the mainstream inhalers in domestic and foreign markets, including capsule-based, disc-based, blister-based, and reservoir-based inhalers. Leveraging the full set of R&D equipment and experienced team, we can provide a range of services, such as design and development of dry powder inhaler, 3D printing, product design, numerical simulation, die sinking and injection, automatic assembly, and assembly line design. 

Inhal innovatively applies the fluidized bed technology to the quantitative packaging of ultra-fine powder for pure powder without excipients particularly. It uses technologies protected with independent intellectual property rights (China Patent ZL02825232.2), including the rotating fluidized bed, auxiliary fluidization technology, alternate switching of gas distributors, fluidized bed walls and gas discharge ceilings, to obtain uniform and fully fluidized gas-solid suspensions, and pass the gas-solid suspension while maintaining the density and shape of the gas-solid suspensions. The method of constant volume or constant flow rate realizes accurate powder measurement. This innovation keeps the fluidization uniformity of gas-solid suspended matter higher than 95%, quantifies 25-2000 micrograms per does, and keeps the average error below 7.5%.
